LEE s. cHAnwIcK, on SHAKER HEIGHTS, AND MARC nn'sEK, or cLnvELAnnHEIeHrsQ OHIO, ASSIGNGRS 'ro PERFECTION STOVE COMPANY, on CLEVELAND, OHIQ'A: 001a- PORATION OF OHIO CLEANING DEVICE FOR- LIQUID-FUEL BURNEBS Application filed June 2,

- This invention relates to improvements in the class of devices disclosed and claimed in Letters Patent Nos. 1,487,206 and 1,549,506, granted, respectively, to one of the present 5 applicants, Lee S. Chadwick, on March 18, 1924, and to the other applicant, Marc Resek, on August 11, 1925.

The primary purpose of the present invention is to'provide a cleaning device for llquld 1 fuel burners ofthe class involving a wick and a wick guide, and that will, in one operation, trim the wick, and wipe char or otherforeign matter from the wick guide or other parts of the burner. I 1 k The device is intended for use especially with tubular burners wherein a cylindrical wick isdisposed between inner and outer wick tubes, the'tubes thus serving as the wick guide.

Suitable mechanism is incorporated in the burner for raising andlowering the wick, and in some types ofburners wherewlth our 1mproved cleaning ClBVlCG 1s lntended to be used,

there isautomatic wick stop mechanism. An

example of such a burner will be found in the second mentioned of the patents above referred to. I

WVhere the term trim or trimming is used herein, it is'intended to mean a removal of the char from the burned portion of the wick, or an actual cutting of the burned part of the wick, or both; and the term wipe or wiping, excepting where otherwise restricted by the context, is employed in its broadest sense and embraces scraping or brushing.

Further objects of the invention are to provide a device characterized by any one or more of the features ascribed to the wick cleaners of the above mentioned patents and which incorporates means for wiping one or both of the wick tubes or other burner parts; to provide a relatively simple and inexpensive arrangement for incorporating the wiping means in the wick cleaner; to provide a construction permitting quick and easy replacement and adjustment of the wiping element, together with other and more limited objects which will appear as this description proceeds, reference being had to the accompanying drawings wherein similar reference 1927. Serial No. 195,915.

proved cleaning device as constructed for use with a well known type of'tubular burner; Fig. 3 p is a central vertical section through the device at right angles to the plane-of Fig.

1, and through the upper portionofa burner to which the device is applied; Fig. 4 is a detail of the-means for securing one end ofthe wiping element to the body of thetdevice; Figs. 5 and 6 are views similar to Figsxl and,

. 2, respectively, of the device as constructed for use with a familiar type of tubular burner involving wick stop mechanism; Fig. '17 is a Vertical section, at right angles to the plane of Fig. 4, through the device and the adjacent part ofa burner towhich it is applied;

Fig.8 is a detail showing the mannerof con necting the wiping element tothe body ofthe device in the last mentioned construction;

Fig. 9is a bottom plan View ofa modification of the invention; and Fig. 10 is a section on the line 1010 of Fig. 9.

Burners of the type wherewith the present embodiments of the invention are designed for use comprise inner and. outer wicktubes 1 and 2, respectively between which a cylindrical wick 3 is guided. Detailed illustra tion of the burner further than that afforded by Figs. 3 and 7 is deemed unnecessary in this conenction since such burners are well known, although itrnay be explained, briefly, that the tubes 1 and 2 are joined together at their lower ends so as to enclose between them an annular reservoir that is supplied with fuel through suitable connections, and wick raising and lowering means is associated with the structure for adjusting the wick vertically within the space between the tubes. Air distributing members or flame spreaders are employed with burners of the class in question and, in the particular type of burner illustrated in Fig. 3, the flame spreader. (not shown). is designed, to rest upon an annular flange4 of a member 5 to which member the flame spreader is adapted to be detachably connected to avoid its being lifted to-any appreciable extent by the engagement of the i of ithe aforesaid members and a trimming part between the formerparts; that is dis-f posed in operative relation to the burned portion of'the wick when said formerparts bear the aforesaid relation to ithe'membe'rs, and
